■ Basal Trunk Spray Using Safari -- Instructional video produced by Valent Corporation demonstrates how to do basal trunk spray with Safari 20 SG. Although it features ash trees instead of hemlocks, the technique is the same. One can see that it's rather easy to do, using a low-flow setting and being careful to apply it from about 5 feet high on the trunk to about 6 inches above the ground. (Wish it had shown the user wearing goggles and a mask -- always a good idea when working with chemicals!) 2010

Here are links to some valuable on-line resources and to some other nonprofit organizations we're aware of that have hemlock-saving goals, provide reliable hemlock-related information, and/or are actively engaged in the hemlocks vs. woolly adelgids battle. This list is by no means all-inclusive, so if you know of others that are environmentally informative and would benefit our community, please let us know. And thanks!
